Abstract
An increasing number of patients with hepatocellular carcinoma (HCC) are undergoing evaluation for listing for liver transplantation. Criteria for selection require ongoing review for suitability. A consecutive series of 40 patients with HCC within the standard Milan criteria (single tumors n = 19 < 5 cm, or up to 3 tumors < 3 cm) and beyond (Extended Criteria; single tumors n = 21 < 7.5 cm, multiple tumors < 5 cm) underwent liver transplant with a sirolimus-based immunosuppressive protocol designed to minimize exposure to calcineurin inhibitors and steroids. At 44.3 +/- 19.3 months (mean +/- standard deviation) follow-up, 1- and 4-year survivals (Kaplan-Meier) are 94.1 +/- 5.7% and 87.4 +/- 9.3%, in the Milan group, respectively, and 90.5 +/- 6.4% and 82.9 +/- 9.3% in the Extended Criteria group, respectively. Five patients died during follow-up, only 1 from recurrent HCC. Five tumor recurrences have occurred at median 17 (mean 22 +/- 17) months posttransplant, 1 in the Milan group and 4 in the Extended Criteria group. Median survival in the patients with recurrent tumor is 42 months (mean 45 +/- 25), and the median postrecurrence survival is 15.5 months (mean 23 +/- 16). The rate of patients who were alive and free of tumor at 1 and 4 years is 94.1 +/- 5.7% and 81.1 +/- 9.9%, respectively, in the Milan group and is 90.5 +/- 6.4% and 76.8 +/- 10.5%, respectively, in the Extended Criteria group. Five patients had sirolimus discontinued for toxicity, while 24 of 35 surviving patients have sirolimus monotherapy immunosuppression. In conclusion, the Milan criteria for liver transplantation in the presence of HCC can be carefully extended without compromising outcomes. This sirolimus based immunosuppression protocol appears to have beneficial effects on tumor recurrence and survival with an acceptable rate of rejection and toxicity.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
